>>4322210I really like the 17 1.8, especially if you get a good copy from the later Vietnam production run, or even a good China one- satisfying rendering, usable through the frame once stopped down a little, and autofocus is lightning-quick (on an Olympus body, anyway) plus it's got the neat little manual focus clutch ring. You're right that it definitely isn't pocketable, though- it weighs almost nothing but from mount to filter threads it's thicker than my EM5 itself. Plus, the focus clutch is fun and all- and fun is an important reason in picking equipment, IMO- but unless you're using it regularly to quickly set the lens to a specific pre-set focal distance, you can just run S/CAF+MF and use the focal ring on any old lens after it auto focuses to refine it. And it definitely isn't the sharpest of the short primes, at least the old models, even a good copy is pretty much just "okay" if you're the pixel-peeping type. Also it WILL throw up blue ghost images if you shoot into the sun, rows of LEDs, street lights, etc. I got lucky with mine and got a deal that made me feel like I stole it, so it was worth it to me- if I was paying the as-new asking price, I'd probably go for a used Pana Leica 15 instead.
The 20mm is highly praised for good reason but focus speed is lethargic in comparison to the other shorty primes; the 14 sounds like it would be about right for you with its even more compact size, and it is a bit slower than the 1.7/1.8 primes but just as sharp from the get-go and remember you've got excellent IBIS to make up for it in shutter speeds. I'm leaning towards that as a recommendation but like the other anon said, length is the most important thing (you can always crop in, but can't always step back further in a given place) so spend a while with your zoom set at those lengths and see what all you end up liking the most. Hell, take a few shots of the same things/same day/same etc with your zoom set to 14/17/20 and see what tickles your fancy the best.
